Abstract:
   The Real-time Transport Protocol (RTP) is widely used in telephony,
   video conferencing, and telepresence applications.  Such applications
   are often run on best-effort UDP/IP networks.  If congestion control
   is not implemented in these applications, then network congestion can
   lead to uncontrolled packet loss, and a resulting deterioration of
   the user's multimedia experience.  The congestion control algorithm
   acts as a safety measure, stopping RTP flows from using excessive
   resources, and protecting the network from overload.  At the time of
   this writing, however, while there are several proprietary solutions,
   there is no standard algorithm for congestion control of interactive
   RTP flows.

   This document does not propose a congestion control algorithm.  It
   instead defines a minimal set of RTP circuit breakers: conditions
   under which an RTP sender needs to stop transmitting media data, to
   protect the network from excessive congestion.  It is expected that,
   in the absence of long-lived excessive congestion, RTP applications
   running on best-effort IP networks will be able to operate without
   triggering these circuit breakers.  To avoid triggering the RTP
   circuit breaker, any standards-track congestion control algorithms
   defined for RTP will need to operate within the envelope set by these
   RTP circuit breaker algorithms.
